HOWARD LYON, OF GLOUCESTER CITY, NEW JERSEY, ASSIGNOR TO WELSBACH LIGHTCOMPANY, A CORPORATION OF NEW JERSEY.

GAS-BURNER.

Specification of Letters Patent. Patented Allg. 29, 1911.

Application led October 7, 1910. Serial No. 585,773.

To all whom 'it may concern:

Be it known that I, HOWARD LYON, a citi- Zen of the United States, and aresident of Gloucester City, in the county of Camden and State of NewJersey, have invented certain new and useful Improvementsin Gras-Burners, of which the following 1s a description.

My invention relates to incandescent mantle gas burners of the invertedtype and provided with an electric ignition filament supportedpreferably in an ignition chamber carried by a canopy above the burnerhead and communicating with an aperture in said canopy, as disclosed andclaimed in my applications Serial No. 541,600, filed February 2, 1910,and No. 566,408, filed June 11, 19.10.

' The present invention has for its object the provision of means fordirecting the flow of gas from the burner head into the igniter wherebythe time required for ignition is lessened, and also means forprotecting the ignition filament against currentsof air occurringoutside of the lamp and which tend to retard or prevent ignition.

In order that the invention may be more clearly understood, reference ishereby made to the accompanying drawing in which- Figure 1 is a bottomplan view ofl a gas burner embodying my invention, Fig. 2 is a sideelevation thereof, partly in section, and Fig. 3 is an elevation of theigniter viewed at right angles to Fig. 2 and partly in section.

The gas burner shown comprises a Bunsen tube f provided with the usualgas check Z), air inlets c, flash diaphragm CZ, globe holder e, andmantle holder g. The globe holder e is in the form of a canopy orinverted funnel having large openings it for discharging the heatedproducts of combustion. Near the center of the globe holder and atsubstantially the highest point is an opening 1 above which is mounted anipple 2 having a flange 3 which is secured by rivets a to the canopy e,the bore of said nipple registering with said opening. Upon the nipple 2is mounted a vertical tube 4 secured by a set screw 5. The walls of thetube 4 are cut away intermediate its ends forming two large rectangularopenings 6 and 7. Atthe bottom of these openings is a baffle plate 8extending across the bore of the tube and composed preferably of somenon-oxidizing substance such as Monel metal which does not scale and iswell adapted for the purpose, its composition being approximately 74 to75% nickel, 24 to 25% copper, 1 to 2% iron.

The upper end of the tube 4 is closed by a plug composed of a metalsleeve 9 secured by a set screw 10, and an insulating bushing 11 settherein and through which passes a headed conducting bolt 12 secured bya nut 13. This nut has a passage 14 for receiving a conducting wire 15and a set screw 30 for securing the same. A very fine wire 16 ofplatinum or platinum alloy is secured at its ends to the supportingconductors 17 and 18, one of which is soldered to the head of the bolt12 and the other to the sleeve 9. The wire 16 is straight, or may beformed with a partial spiral at the center as disclosed in myapplication Serial No. 585,772, filed October 7, 1910, and extendshorizontally across the axis of the tube 4 and parallel to the edges ofthe baflie plate 8, and to the planes of the openings 6 and 7.

Upon the Bunsen tube f is mounted a spoon shaped deflector 19 whichextends entirely across the central portion or axis of the lamp in aninclined position as shown, the lower end being below the level of theopenings h and the other end adjacent the aperture 1. This deflectorcauses an i11- flammable mixture to pass through the aperture 1 into theignition chamber formed by the tube 4, within a very short time aftert-he gas is turned on. Ahemispherical shield or guard 20 having asecuring flange 21 incloses the tube 4 in such position as to completelyprotect the lament from air currents outside of the lamp and which byunduly cooling the ignition filament and diluting the gas mixturesurrounding the same tend to retard or prevent ignition. The shield 20is secured by the set screw 5.

Having now described my invention, what I claim is:

1. In a gas burner, a downwardly extending supply pipe, a canopysurrounding the same and having an aperture eccentric thereto, anignition chamber communicating with said aperture, a filament withinsaid chamber, a baffle between the filament and said aperture and adeflector within the canopy for deflecting the ascending gas to saidaperture.

2. In a gas burner, a downwardly extending supply pipe, a canopysurrounding the same and having an aperture eccentric there to, anignition chamber communicating with said aperture, a filament withinsaid chamber, a baffle between the filament and said aperture and adeflector carried by said pipe within the canopy for defiecting theascending gas to said aperture.

3. In a gas burner, a downwardly extending' supply pipe, a canopysurrounding the same and having an aperture eccentric there to, anignition chamber communicating with said aperture, a filament withinsaid chamber, a bafHe between the filament and said aperture and aninclined deflector carried by said pipe within the canopy for deflectingthe ascending' gas to said aperture.

4. In a g'as burner, a supply pipe, acanopy surrounding the same andhaving' an aperture eccentric thereto, an igniter communicating withsaid aperture, and an inclined spoon shaped deflector within the canopyfor deflecting the ascending gas.

5. In a gas burner, a supply pipe, a canopy surrounding the same andhaving one or more large openings for permitting the escape of productsof combustion and a relatively small aperture, an igniter communicatingwith said small aperture, and a deflector within the canopy fordeflecting the ascending gas to said aperture, said deflector extendingfrom a point below said large opening to a point adjacent said smallaperture.

6. In a gas burner, a supply pipe, a canopy surrounding the same andhaving one or more large openings for permitting the escape of productsof combustion and a relatively small aperture arranged on the oppositeside of said canopy from said large openings, an igniter communicatingwith said small aperture and a deflector within the canopy so arrangedas to deflect the ascending gas away from said large openings and towardsaid small aperture.

7. In a' gas lamp, a supply pipe, a canopy surrounding the same andhaving an aperture, an ignition chamber communicating with said apertureand having one or more windows opening directly to the atmosphere, afilament adjacent said window, and a shield outside of said chamber soplaced as to protect the filament against currents of air from theoutside.

8. In a gas lamp, a supply pipe, a canopy surrounding' the saine andhaving an aperture, an ignition chamber communicating with said apertureand having a window opening' directly to the atmosphere, a baille, afilament above said baffle and adjacent said window, and a shieldoutside of said window.

9. In a gas lamp, a supply pipe, a canopy surrounding the same andhaving' an aperture eccentric thereto, a tubular ignition chambercommunicating with said aperture and having a window opening directly tothe atmosphere, a filament therein, and a shield surrounding saidigniter adjacent said window.

l0. In a gas lamp, a burner head, an ignition chamber in the path oi thegas issuing therefrom, and having a window opening into the atmosphere,a filament within said ignition chamber adjacent said window,and ashield outside of' said window for protecting said filament againstatmospheric air currents.

This specification signed and witnessed this 5th day of October, 1910.
